I already saw that, thanks. One can assume it has something to do with Adobe AIR, which I had installed, but after uninstalling it, it's still there.
Tried MalwareByte, SAS, NOD32 none of them found file suspicious.
If I block it in Comodo, then Defence shows: Defence+ has blocked (few hundreds!) of this file attempts
File properties shows also nothing.
Any idea?
EDIT: I have deleted the file, but upon restart it's recreated!
EDIT2: stupid me

, this file was made with RunAsDate app I'm using. Sorry folks!
